NITED STATES ATENT HOT-WATER BOILER.

SPECIFICATION forming part of Letters Patent No. 442,566, dated December9, 1890.

Application filed April 5, 1890. Serial No. 346,774. (No model.)Patented in Canada May 2, 1889, No. 31,240.

To aZZ whom it may concern:

Be it known that l, ULRIC BEAUPRE, a citizen of the Dominion of Canada,residing in the city of Montreal, in the Province of Quebec, Canada,have invented certain new and useful Improvements in Hotater Boilers,(for which I have obtained Letters Patent in Canada, dated May 2, 1889,No. 31,240,) and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention has reference to a hot-water boiler composed of sectionsinto which the water circulates, as explained hereinafter, and passesfrom one section to the other through ports or openings arranged asshown below.

The object of my invention is to provide a hot-water boiler having alarge heating-surface to be easy of repairs, compact, and ineX- pensive.

Referring to the drawings, similar letters refer to similar partsthroughout the several views.

Figure 1 is a front elevation shown half in section; Fig. 2, a sideelevation shown half in section; Fig. 3, a section through A B; Fig. 4,a section through C D; Fig. 5, a plan of the fire-box section, shownhalf in section. Fig. 6 is a plan view of one of the sections; Fig. 7, aplan view of the other section; Fig. 8, a section through E F. p

E is the fire-box section, provided with the ordinary door F and thecircular water-space G, exit ports or openings I J, and the coldwaterintake H, which may be a single pipe or several pipes, as foundsuitable. These ports The fire-box proper L is provided with thevertical pieces M, which project out somewhat, the object of these beingto accelerate the draft and also to furnish a suflicient quantity ofwarm air to burn the gases, this being accomplished in the followingmanner: The burning coal is kept away from the sides of the fire-box bymeans of the pieces M, so that there remains a series of spaces betweenthe sides of the firebox Landtheburning coal. Through this space rushesa certain quantity of air, which gets heated in these passages andconsumes the gases in the upperportion of the fire-box, and

as the air meets but asmall resistance through the passages so leftthere is quite a draft produced. On top of this section E is the sectionN, pierced by any number of suitable openings Q. In the interiorof thissection is placed the partitions R R and R, disposed as shown in Fig. 3and for the purposes described hereinafter. This section N is providedwith the projection s, which contains the ports or openings V, W, and X.Next comes the section Y, which is also provided with any number ofsuitable openin c, the interior also having partitions (Z (Z and d,disposed as shown in Fig. 4:, the projection a being provided with theports or openings g, h, and 1'. Now any number of these sec tions can beput in my hot-Water furnace,

provided, however, that they are always put in in pairs and disposed asshown in the drawings.

The sections N and Y are provided on their under surface with thecircular projections m, which serve to provide the spaces at n for thecirculation of the hot gases and smoke, and also by resting against theV projection 19, placed on top of all the sections to secure a goodjoint.

My furnace can be made out of any kind of suitable material and of anysuitable size.

Now to describe the action of my hot-water furnace, I will suppose thecold water entering through the cold-water inlet I-l into the space G,where it circulates around the firebox L and rises through the two portsor openings I and J, which communicate with the ports or openings V andX, which conduct the How along the channels t, provided by means of thepartitions R R, placed between the partitions of the openings Q, intothe interior of the section N, as shown by ar-- rows in Fig. 3, where,continuing to absorb heat, its tendency to rise moves it up the portlV,which communicates with the port 77., placed so as to direct thecurrent into the interior of section Y, as shown by the arrows in Fig.4, where it again absorbs additional heat, and consequently proceedsalong the channel y, formed by the partitions cl cl, and passes up intothe ports g and t, where it again enters the ports V and X of thefollowing section, if another set of sections exist, or, if not, passesdirectly into the delivery-pipe to, which delivers it where required.The small partitions R and cl serve to deviate the current of the water,so as to take the directions shown in Figs. 3 and 4. These sections Nand Y can be joined together in any suitable manner. Now the whole ofthe sections are put upon the ash-pit section A made as shown in Fig. 2.However, between the sections A and E is interposed the grate-section Bprovided with the grates C Having described my invention, what I claim,and desire to secure by Letters Patent,

1. In a hot-water furnace, a section N, provided with the openingsQ,partitionsRRand R, channels 25, and projections 5, provided with theports or openings V, \V, and X, substantially as described, and for thepurposes set forth.

In a hot-water furnace, a section Y,provided with the openings 0,partitions d (l and (1', channels wand projection 6, provided with theports or openings 9,71, and t, substantially as described, and for thepurposes set forth.

3. In a hot-Water furnace, the combination of the ash-pit section Agrate-section B firebox section E, intake-pipe H, with the sections Nand Y, delivery-pipe w, and cover A, substantially as described, and forthe purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.
